invention relates to a, fastening def vice, capable of usejlin numero us different associations but. particularly intended to be applied inconnection with the fastening ':of

window-sash, l

It is an obj ect' of the'inventi'on to provide a device. of this character which, upon" being thrown to operative position, may automatically "assume a locked condition.

A further object of'the invention is that of furnishing a device ofthis type which will, serve, ifdesired', to not alone secure two:

members with which it is associated against relative movement, but'it will also serve to '15 draw such members towards each other and into sealing contact. 7

An additional object is'that of furnishing a lock o-rifa'stening device, the'parts of willjbe relatively 'few in number and indl c viduallyfsimple and. rugged in construction,

these parts being 'largely 'capable of "being manufactured by automatic machinery, and

furthermore, lending themselves to ready assemblage by relatively unskilled labor, .so that an article of this nature is provided operating over "long periods of time. with freedomlfrom mechanical difiicu'lties, and capable of being manufactured at relatively nominal cost.

7 e5 parts, and showingthe same in operative .re-

lation; i

Fig.1 '2 is view of the keeper' ele r y m ngsactlon is exerted by the bolt.

f words, the path of thiss'lot isnot that of "an ment I Fig. 3 is a face View thereof;

Fig. 4 is a partly 'se'ctionalside view of the parts as'shown in Fig. 1, and illustrating th I fastener as applied to windowxsash; I

:Fig. 5 is a partly sectional plan "view of the boltm'ember of the fastening-device,- and r Fig. 6 is an edge view of'the latter.

In these views, the reference numerals 1'0 and 11 indicatethe keeper element and bolthousing member respectively. Each" of these members is preferably formed with a,

centrally bulged POItiOIIfaS at 12, and cerwah these and further objects in mind;

will cam againstthe slot edge, resulting in [18 may becarriedby this arm and is normally pressed inwardly "by means of a 1 spring 19. J i

As shownin Fig.- 6, the ends of the slot 17 are preferably enlarged, as at 20, inorder to accommodate the reduced inner end port-ion 21 of the knob, it being thus apparent that as the outer arm of the bell-crank lever is swung to either of its extreme positions, the knob, under the influence of the spring, will ride 7 within the enlarged portions20 and-thus pre vent any further manipulation of the lever until the knob has been retracted to have its reduced portion 21 withdrawn from the enlargedends 20 of the slot. Thereupon, it 7 Will be apparent that if the lever is swung fto its opposite extreme position, the knob will be automatically projected as soon as the reduced end portion thereof comes in line with the enlarged part of the slot. Now with a viewtocoupling the members 10 and 11 when the fastening device is in operative position, it willbe observed that the bulged portion112 of the member IOpresents an arcuate $101122, it being h'ere'noted that the degree of curve ture of this slot is preferably such that a cam In other are of a circle having as its center the pivot pin 13. Asa consequence, whenthe lever 14' is rocked, the bolt head will freely enter the slot through the enlarged forward end 23 thereof, but; the reduced portion; of thebolt the complementary portions of the members; 10 and 11 being drawn into intimate contact. Thus it will be seen that. if the members l011 are affixed one to each of, for example,

a pair of sash members, these members" will f be drawn towards each other, and a rattling thereof incident to air pressures will be normally prevented.

' Furthermore, it will be apparent that even if an implement is forced between the sash members, the bolt may not be retracted, due to the locking expedient resorted to, and furthermore, these sash members may not be forced to raised or lowered positions by virtue of the enlarged head of the bolt provided to revent this result. 1 V 3 rom the foregoing it will be appreciated that, among others, the several objects specificall aforementioned are achieved. It will, furt ermore, be understood that numerous changes in construction, and rearrangement of the parts, might be resorted to without in the slightest departing from the spirit of the invention as described by the claims.

Having described my invention, what I claim as new and desire tosecure by Letters Patent is v 1. A fastening device including a pair of sheet metal members of substantially constant gauge, a lever pivotally carried by one of said members, the second of said members being formed with a slot eccentrically disposed with respect to the point of pivotal connection of said lever, and means carried by said lever to ride within said slot.

' 2. A fastening device including a pair of members, a lever pivotally carried by one of said members, a bolt carried by said lever and the second of said members being formed with a slot to receive said bolt, said bolt having a head portion extending beyond said slot and a reduced portion riding within the. same and said slot having an enlarged'open end for the passage of said head.

V 3. A fastening device including a pair of members, a lever pivotally mounted by one of said members, neans carried by said lever and cooperating with the second of saidmembers to couple. both of said members against relative movement, a slot formed in the levercarrying member and through which the end of said lever extends, and a spring-pressed knob carriedv by that vend of the lever which extends through saidslot and cooperativev with the edge portions of said slot to prevent movement of said lever with respect to the member with which it is associated.

4. A fastening device including a pair of easing members, a bulged portion forming a part of each of said members, a lever pivotally carried within the bulged portion of one of said members, the'second of said members bein formed with a slot eccentrically disoset l with respect to said lever pivot, a bolt ead carried by said lever and having a reduced portion riding withinsaidslot, and the bulged portion of said first member being also formed with a slot through which the outer end of said lever extends. v V

5. A fastening device including a pair of sheet metal members comprising bodies and bulged portions forming a part of said bodies, a cooperating lever and slot structure associated with said members, one of the parts of said structure being eccentrically disposed with respect to the second of the same whereby as sald lever is shifted along said slot, the members will be drawn into intimate contact and retained against movement with respect to each other. o

,6. -A fastening device including a pair of members, bulged portions forming a part of. each of said members, a lever secured to one of said members, the second of said members being formed with a slot for cooperation with said lever in orderto retain the members against movement when said lever is shifted to a predetermined osition, the lever mounting member being ormed with a slot in the side of its bulged portion, and enlarged arts adjacent the ends of said slot, the end 0 said lever extending through said slot, and a spring pressed knob associated with the end of said lever and projectable into said enlarged portions to prevent a shifting of said lever.
